Berserker Probe is a small vessel of unknown class. The probe sought out civilizations capable of answering each of its questions and eliminates any perceived threat that it encountered. The probe first arrived in Babylon 5 space in January 2260. It initially sent out an unknown transmission, which was translated by the crew. This message contained a promise for cures for diseases, and other advancements in exchange for being able to answer every question it asked. Failure to answer these questions would mean the destruction of their civilization.
